Random sampling is as easy as choosing numbers. Teams use random numbers to create a sample of book lengths from a population of 150 books. The groups continue by developing a technique to create samples to compare from two populations...

Determine whether there is a difference between two grades. Teams generate random samples of two grade levels of individuals. Groups use the mean absolute deviation to determine whether there is a meaningful difference between the...

The 13th activity in a unit of 22 introduces the concept of the interquartile range (IQR). Class members learn to determine the interquartile range, interpret within the context of the data, and finish by finding the IQR using an...

Find the point that splits the data. The lesson presents to scholars the definition of the median through a teacher-led discussion. The pupils use data lists and dot plots to determine the median in sets with even and odd number of data...

Pupils analyze a display of data and review dot plots to make general observations about the highest, lowest, common, and the center of the data. To finish, learners match dot plots to scenarios. 

Students collect data about dairy production. In this geometry lesson, students formulate and model problem solving. They collect data and plot it on a graph.

For some, probability is a losing proposition. The assessment item requires an understanding of fraction operations, probability, and fair games. Pupils determine the fractional portions of an event. They continue to determine whether...

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.  

Explore different representations of numbers. Scholars convert between fractions, decimals, and percents, and then use these conversions to plot the values on a horizontal number line.

Functions require an input in order to get an output, which explains why the answer always has at least two parts. After only three multi-part questions, the teacher can analyze pupils' strengths and weaknesses when it comes to...

Working with transformations allows the class to take a turn for the better. The short assessment has class members perform transformations on the coordinate plane. The translations, reflections, and rotations create pattern designs on...

Mortgages, payments, and wages correlate with each other. The short assessment presents scatter plots for young mathematicians to interpret. Class members interpret the scatter plots of price versus payment and wage versus payment for...

The class braids irrational numbers, Pythagoras, and perimeter together. The mini-assessment requires scholars to use irrational numbers and the Pythagorean Theorem to find perimeters of rugs. The rugs are rectangular, triangular,...

Just what does it take to show two rhombuses are similar? The assessment task asks pupils to develop an argument to show that given quadrilaterals are rhombuses. Class members also use their knowledge of similar triangles to show two...

In this math worksheet, students work at home with a family member on a graphing activity. Students count the number of cans, glass jars, boxes and bags in the pantry. Students make a bar and a line graph to represent the data.

Learners define mode, median and mean, and perform mathematical operations to determine these 3 terms. In this statistics/math lesson, students practice memory strategies to help distinguish between mode, median, and mean. Learners apply...

Ninth graders participate in a lesson focused on the concept of basic statistics. They find the mean, median, and mode of different data sets. More advanced students could practice creating a bell curve from the data.

Sixth graders explore the math concept of probability. In this probability lesson, 6th graders examine visual examples of finding probability. Students also practice solving problems that their instructors model.

Young scholars review for the Regents Exam. In this math lesson plan, students review core concept for the Regents exam by working a variety of problems. A printable worksheet is provided.

Students examine a soccer league final standings chart and then answer 12 questions based on the information provided. They calculate some answers in both fractions and percentages.

Young scholars convert decimals and fractions to percents. In this introductory percents lesson, learners work with equivalent fractions and learn to draw ratios. They recognize how to change a fraction to a percent.

Students demonstrate how to find the probability of events. In this probability lesson, students use colored tiles in a paper bag and randomly select one at a time to record the probability.

Connect ratios, probability, and combination outcomes with a challenging activity idea. It guides your learners through probability of an event as fractions or ratios, on a number line, and with correct vocabulary. The class will be...

Help plan a road trip with linear equations. Scholars consider two different rental car companies and write equations representing the cost for each company. They graph the system of equations to determine the conditions under which each...
